AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
355 PM PDT FRI JUL 13 2012

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT...WATER VAPOR SATELLITE
SHOWS A LOW CENTER MOVING SOUTHWARD ALONG WESTERN WASHINGTON. TO THE
EAST...A PLUME OF MOISTURE IS STREAMING NORTHWARD FROM THE MONSOONS
IN THE DESERT SOUTHWEST. OUR FORECAST AREA LIES IN BETWEEN THESE
FEATURES LEADING TO A SLOT OF DRY AND MORE STABLE AIR. EXPECT THIS
TO CHANGE AS THE LOW PRESSURE SYSTEM CONTINUES TO MOVE SOUTH TOWARD
WESTERN OREGON TONIGHT. SOME CUMULUS ARE BEGINNING TO BUILD OVER THE
MOUNTAINS IN GRANT AND BAKER COUNTY AS WELL AS IN WALLOWA. THERE IS
ALSO A GROUP OF CUMULUS BUILDING OVER THE EAST SLOPES OF THE
WASHINGTON CASCADES. BOTH OF THESE LOCATIONS AS WELL AS INTO THE
BLUE MOUNTAINS HAVE THE POTENTIAL TO DEVELOP THUNDERSTORMS THIS
AFTERNOON AND EVENING. WHILE INSTABILITY FROM DAYTIME HEATING WILL
DECREASE AFTER SUNSET...MID LEVEL INSTABILITY ASSOCIATED WITH A
DISTURBANCE MOVING AROUND THE LOW WILL KEEP THE POTENTIAL FOR SHOWER
AND THUNDERSTORM DEVELOPMENT GOING OVERNIGHT. THIS WILL BRING
UNSTABLE AIR FROM NORTHEAST OREGON INTO THE COLUMBIA BASIN AS WELL
AS BACK INTO THE EAST SLOPES OF THE CASCADES AND THE COLUMBIA RIVER
GORGE.

THE LOW CENTER WILL THEN MOVE EAST ACROSS THE AREA ON SATURDAY
BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS EVERYWHERE. THE ONE
LOCATION THAT WILL SEE LESS ACTION WILL BE CENTRAL OREGON NEAR THE
CASCADES AS THE SYSTEM PASSES JUST NORTH OF THEM. WITH SOME DECENT
SHEAR...STORMS COULD BECOME STRONG ACROSS NORTHEAST OREGON AND SPC
HAS PLACED THAT AREA INTO A SLIGHT RISK FOR SEVERE THUNDERSTORMS FOR
SATURDAY AFTERNOON. AS THE UPPER LEVEL FLOW INTERACTS WITH THE
MOISTURE STREAM TO THE EAST...STORMS WILL GRADUALLY BECOME MORE WET
WITH BRIEF HEAVY RAIN POSSIBLE. THE SYSTEM WILL PROVIDE ENOUGH
DYNAMICS TO KEEP CONVECTION GOING OVERNIGHT.

THE SYSTEM WILL MOVE EAST ON SUNDAY LEADING TO A DECREASE OF SHOWER
AND THUNDERSTORM POTENTIAL FROM WEST TO EAST DURING THE DAY. ANOTHER
TROUGH OF LOW PRESSURE WILL THEN DROP SOUTHWARD LATE SUNDAY AND
BEGIN TO SPREAD THE CHANCE OF SHOWERS AND THUNDERSTORMS AREAS ALONG
THE EAST SLOPES OF THE CASCADES OVERNIGHT SUNDAY. DMH

.LONG TERM...MONDAY THROUGH FRIDAY. THE UPPER LOW IMPACTING THE
REGION THIS WEEKEND WILL MOVE OFF TO THE EAST AND BE REPLACED BY
ANOTHER LOW MOVING SOUTHWARD FROM BRITISH COLUMBIA. THIS SYSTEM WILL
BRING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. MODELS HAVE
DIFFERENT SOLUTIONS TO THE EXACT LOCATION OF THE LOW SO HAVE TAKEN A
COMPROMISE FOR NOW. THE POSITION OF THE LOW AND THE AVAILABLE
MOISTURE AND INSTABILITY SUPPORT A CHANCE OR SLIGHT CHANCE OF
THUNDERSTORMS EACH DAY. HIGH TEMPERATURES WILL REMAIN NEAR NORMAL
WITH 80S TO LOWER 90S. BY THURSDAY AND FRIDAY THE PATTERN BECOMES
MORE OF A TROUGH CENTERED OFFSHORE WITH A SOUTHWEST FLOW ALOFT OVER
THE AREA. THIS WILL CONTINUE TO SUPPORT ISOLATED THUNDERSTORMS WITH
SEASONAL TEMPERATURES.   94

&&

.AVIATION...00Z TAFS. UPPER LOW WILL MOVE SLOWLY ACROSS THE REGION
OVER THE NEXT 24 HOURS. THIS WILL GENERATE SCATTERED SHOWERS AND
THUNDERSTORMS ESPECIALLY LATER TONIGHT INTO SATURDAY. THE HIGHER
CHANCE OF PRECIPITATION WILL BE OVER THE COLUMBIA BASIN TAF SITES
WEST TOWARD YKM DLS. CLOUDS WILL INCREASE IN COVERAGE WITH CEILINGS
BECOMING 050-100. BRIEF LOWER CEILINGS LIKELY WITH SHOWERS AND
STORMS. SURFACE WINDS MAINLY 5-15KT EXCEPT 10-25KT AT DLS.
THUNDERSTORM OUTFLOWS COULD GENERATE LOCALLY STRONGER WINDS.  94

&&

.FIRE WEATHER...A LOW PRESSURE SYSTEM WILL MOVE THROUGH THE REGION
OVER THE NEXT SEVERAL DAYS. UNSTABLE CONDITIONS WILL LEAD TO THE
DEVELOPMENT OF THUNDERSTORMS THIS EVENING. STORMS WILL FORM OVER
EASTERN OREGON THIS EVENING AND THEN MOVE INTO CENTRAL WASHINGTON BY
SATURDAY MORNING. THUNDERSTORM ACTIVITY WILL PERSIST ACROSS
NORTHEAST OREGON AND EASTERN WASHINGTON THROUGH SATURDAY NIGHT.
COVERAGE WILL DIMINISH ON SUNDAY BUT SOME STORMS MAY LINGER FROM THE
BLUE MOUNTAINS EASTWARD. ALTHOUGH LIGHT TO MODERATE RAIN IS
EXPECTED TO REACH THE GROUND...ABUNDANT LIGHTNING COULD CAUSE
SEVERAL NEW FIRE STARTS...ESPECIALLY IN THE FINER FUELS BELOW 4000
FEET. RED FLAG WARNINGS HAVE THEREFORE BEEN ISSUED FOR MUCH OF THE
AREA BEGINNING THIS EVENING AND LASTING THROUGH SUNDAY.  TRIMARCO
